CONSTANTINO PELLEGRINO, BOTH, OF BROOKLYN,

Application filed August a, 1928. Serial No. 297,608.

My invention relates to automatic gas' .i niters and more-particularly to an igniter dapted, to ignite said burner initially and tore-ignite said burner automatically should the "flame be extinguished for any cause.

The flame of a gas. burner, such-as the burner of a gas range commonly used for domestic cooking, is frequently extinguished by Water which boils over, by drafts, etc.. The attendant is often unaware that the flame has absent from theroom or house at the, time,

so that theburner is not immediately reignited. In such event, the'gas escapes into the room and the atmosphere becomes con- .taminated with a poisonous and explosive gas whereby the lives of persons in the room or elsewhere in the house, and particularly of sleeping persons, are endangered.

It is an. object of the present invention to provide an automatic igniter which will automatically re-ignite a burner should the flame of the latter be accidentally extinguished, the igniter serving also to ignitethe burner initially upon operation of the usual hand valve.

It is a further object of the present invention to provide an automatic igniter -which can be readily attached to burners now in use, which is simple and sturdy in construction, is inexpensive to manufacture, and is positive and reliable in operation.

Other objects will appear from the following description and the features oflnovelty will be pointed out in the appended claims.

In the drawing which shows, by way of example, a preferred form of my invention without defining its limits,

Figure 1 is a side elevation of a burner. with my automatic igniter in position there on;

Figure 2 is a similar view, partly in section; and

' Figure 3 isa plan view of the same. Referring to the drawing,'10 indicates a 'burner of any usual or known construction having a feed-pipe 11 connected thereto and controlled by any suitable valve (not shown). The gas flowing through the pipe 11 escapes through and burns at the openings 12 in theburner in the wellsknown manner;

been put out, or he or she may be Mynovel automatic igniter is composed" of amember 13 in the form of an elbow having a tubular vertical section 14 which passes through the wall of the pipe 11 and' projects into the interior thereof. The section 14 terminates at its lower end along a plane which is inclined to the vertical and is thereby provided with an enlarged inlet in the path of the gas flowing through the pipe ll. The horizontal section 14' of the member 13 is' formed of a tubular portion whose lower half has been 'cut away, along a plane atanangle to the=axis of such section thereby providing a curved hood or f shield which is elevated relatively to the burner 10. The upper portion of the vertical section 14 is completely closed except for an approximately horizontal opening 15. The member 13 may be connected to the pipe .11 many desired way, as by drillinga hole in said pipe and tapping the same so as to cooperate with. an external thread on the section 14, or by welding the parts together,

etc.

A pilot tube 16, which is connected to the gas supply line in advance of the valve controlling the pipe 11, is operatively associated with the member 13 and terminates at a point adjacent and slightly belowvthe open-.

ing 15. Where a number of burners are employed, each of them will have a separate pilot tube and all of the latter may be con trolled by a single needle or other valve to regulate the quantity of gas flowing thrpugh the tubes. a v

The. operation of my automatic igniter is as follows: The gas escaping from the pilot tube 16 burns continuously in front of the opening 15, as this tube is not controlled by the valve in the pipe 11. Upon opening of the valve in said pipe 11, the gas will flow to the burner 10 and at the same time ,a column of gas will rise in the vertical vessel being heated, or by a draft or for any other reason, the burner will be immediately re-ignited by the jet of flame issuing from the opening D. The pilot light is protected 1 against water and drafts by the curved hood or shield 14, so that 'so long as the .gas is flowing to the burner .10,- a jet of flame will issue from under the hood 14 and strike the burner 10.-

Variations from the specific form shown and describedmay be resorted to within the scope of "the appended claims without departing from the spirit of my invention.

I claim: A 1. The combination with a controlling valve thereto; of an angular I member; comprising a'substantially tubular section projecting into said pipe and an arched hood section at an angle to said tubular section, the latter having 1 an opening above the level of said burner for directing a jet of gas beneath said hood a gas burner having a feed-pipe for conducting gas from a controlling valve thereto; of an angular deflector of two sections having one section thereof partially projecting into said pipe transversely thereof and provided with an opening substantially parallel to said pipe for-directing a jet of gas externally thereof and toward said burner,' the other section of said deflector forming a hood extending along said pipe in the direction of the burner, and a pilot adjacent said opening.

3. The combination with a gas burner having a feed pipe for conducting gas from acontrolling valve thereto; of an angular deflector of two sections having one section thereof projecting into said pipe and providedadjacentits outer extremity with an opening for directing'a jet of gas externall of said pipe toward said burner, a pilot ad jacent said jet, and a hood forming the other section of said' deflector and rojecting from the outer extremity of the rst named section in the direction of said burner and above'said pilot. I In testimonvwhereof I have aflixed my signature.
